The Apprentice Publisher's Summary

Fionn Killough is a Killough Company man in both blood and loyalty. Sloan—his uncle and mob boss—is the only father figure that Fionn has had, and he would do anything for him. But when Fionn is assigned to sniff out a rat in the Company, he hesitates for one reason—Daire.

Daire Reardon is the Company’s second-in-command and the man Fionn loves. Fionn has spent eight long years yearning for a relationship with Daire, but Daire refuses to give him more than his body. Sloan doesn’t know the entire truth about their history, and Fionn would never reveal his darkest secret. As much as Fionn tries, he can’t hide his feelings for Daire, even if the other man won’t acknowledge them.

Daire knows Fionn wants more. He’s known since the very beginning of their physical relationship. As much as he wants to, Daire can’t bring himself to admit his feelings for Fionn, not when he has a secret of his own. The more time he spends with Fionn, the more his own loyalty to Sloan and the Company are put to the test.

The Killough Company is going to war. They’re being attacked on all sides. To succeed in their mission to find the rat, Daire and Fionn need to deal with their feelings before they destroy them for good.

The Apprentice is an MM mob romance. It has morally-gray characters who would do anything to protect the man they love.
